please, let players choose maps and modes to have a priority for quick match. There are some tedious maps and modes that could be not preferrable for player. Yet, he must play them when quick match was found, or else he will be banned. to summarize:

1. overall, levels or priorities for maps: 0 (ban), 1 (okay), 2 (preferrable)
2. modes (the same)
3. settings: up to 1/2/3 wins (to change maps quickier), up to 1/2/3/4/5/6 goals (depending on map), up to 1/2/3/4/8 teams (in the last standing mode), change animal between maps (no, okay, preferrable)

this way players will always find other players to play on maps their want.
